Final answer:
Juliet agrees to marry Paris to avoid conflict with her parents and to buy time for her plan with Friar Laurence to reunite with Romeo.
Step-by-step explanation:
Juliet tells her father she is willing to marry Paris because she is strategizing to avoid the marriage to Paris without directly disobeying her parents. This happens after a tumultuous conflict where her father, Lord Capulet, demands her to marry Paris, threatening her with disownment and public shaming. Juliet, seeking to buy time and to placate her father, pretends to agree to the marriage while internally planning with Friar Laurence to reunite with her true love, Romeo, who has been banished.
